Reading Text Files

Hey, I am currently trying to read a text file, which looks something like this:
1
2
3
4
.
.
a
b
c
.
.
.
I would like to read the integers and characters into the same array. I tried using a char, string.. hoping that it would be recognized as a string or something but I continuously get the compiling error "cannot implicity convert 'int' to 'string'. Does anyone know what im talking about and if so how could i get around this problem.
Thanks in advance.

Im getting a few errors and im not sure if im missing something.. i dunno ive been staring at this with a blank face for a while now too. if you spot something please give me a shout.
Thanks in advance again.

Well try to use "\\" in place of "\" and it will work out...
in c# if u r using \ as a string , always make sure u follow either of the 2:
1>"\\"
2>@"\"
under this situation i would suggest u to use the first option.
